Definitions
- the present invention relates to a method for determining the degree of crosslinking of at least one provided on a support plate resin layer according to the preamble of claim 1.
- Wood-based panels as support materials are used in various fields and are widely used.
- wood-based panels are, inter alia, of use as floor panels, e.g. in the form of laminate flooring, known.
- Such material plates are usually made of wood fibers, wood chips or strands.
- Decorative resin-impregnated papers can be pressed onto the surface of the material plate for this purpose, or laminates which are first pressed from a plurality of resin-impregnated papers into a laminate can be glued onto a wooden material. Decors can also be applied directly to the wood-based panel, which are then sealed with a resin or varnish.
- the resin-impregnated papers are obtained by impregnating the paper layers in water-containing synthetic resins on impregnation channels with subsequent drying in a drying tunnel.
- the impregnates contain a defined amount of resin and a defined residual moisture after the impregnation process.
- the main field of application for impregnates is the production of decorative surfaces. Further applications for impregnated papers are the wear protection, the reinforcement and the guarantee of freedom from distortion (stress symmetry).
- different papers and resins are used. For example, if it is the creation of a decorative surface, printed decor papers impregnated with melamine and / or urea resins are used have been dried to a defined residual moisture.
- overlays ⁇ -cellulose-containing papers
- phenolic resin kraft papers are used for reinforcing purposes.
- the resins used for the impregnation of paper layers or also for the direct coating of other carrier plates undergo various states of polymerization and crosslinking in these processes.
- melamine-formaldehyde monomers are subject to the addition of a suitable catalyst, preferably an acid, the polycondensation, which leads to the linking of the monomers via ether and methylene groups and to the formation of higher molecular weight precondensates and polycondensates (see Scheme II).
- a suitable catalyst preferably an acid
- Precondensates and polycondensates differ in terms of their molecular weight and their solubility.
- the low molecular weight precondensates may still have limited solubility in water, while the higher molecular weight polycondensates are insoluble.
- the limited water solubility of the precondensates is i.a. due to still free methylol groups and the low degree of crosslinking of the mostly linear oligomers.
- the precondensates are thus a polymerization intermediate.
- impregnated paper layers for the finishing of wood-based panels, e.g. To higher quality floor panels, it is desirable that the impregnating resin is not fully cured, but is preferably still in the partially crosslinked B-state. This allows for further processing in the press still a flow / filming in combination with the cross-linking of synthetic resins.
- the humidities of impregnates are usually 5-7 wt.% Depending on the intended use.
- the determination of the residual moisture is the only relevant quality test carried out on an impregnation channel.
- the invention is therefore based on the technical problem of developing a method which overcomes the above-mentioned deficiencies.
- the process should allow analysis without material destruction or consumption.
- An analysis should be possible on-line in an impregnation plant.
- To test pallets with impregnates, a mobile procedure should be available.
- the testing of the curing of resins on wood-based panels should also be possible.
- a key point should be a quick measurement including data analysis.
- the present method makes it possible to determine the degree of crosslinking of the precured resin layer provided on the support material, the degree of crosslinking preferably corresponding to the degree of crosslinking of a resin whose cure has been interrupted in the state of incomplete polymerization. i.e. is in B state. Accordingly, the precured resin layer to be measured is not completely dried out, but rather is in a predried or pregelled state. In this pre-dried state, the resin is still flowable and can be further crosslinked in a further processing.
- the precured or pre-dried state of the resin layer allows i.a. the application of further functional layers to the already existing resin layer at a later time.
- the present method of determining the degree of crosslinking of a precured resin layer provided on a substrate using NIR spectroscopy offers an alternative to the time-consuming and costly tests of VC value and residual moisture value described above.
- the determination of the degree of crosslinking is carried out using an NIR measuring device in less than one minute, which allows a high sample throughput.
- the measurement is non-destructive.
- the measurement results are stored automatically in electronic form and are available for possible further use.
- samples from several plants can be tested for the degree of hardening in a short time. In this measurement dozens of NIR measurements are performed in one second, so that a statistical protection of the values is guaranteed.
- the NIR radiation is used to produce an NIR spectrum of the precured resin layer provided on the substrate which has peaks specific to the resin layer.
- the NIR radiation is directed to the sample to be analyzed during the measurement, where it interacts with the components of the sample and is reflected or scattered.
- An NIR detector captures the reflected NIR radiation and generates an NIR spectrum that includes the chemical information of the sample.
- the free methylol groups present in a formaldehyde resin are the measurement signal other than the methylene ethers or methylene bridges which form during the curing with elimination of water or formaldehyde.
- the NIR spectrum of a sample coated, for example, with melamine-formaldehyde resin has a distinct broad absorption band with an absorption maximum at approximately 1490 nm. These Band corresponds to the first harmonic of NH groups. At about 1450 nm, a first harmonic of the OH bond of the water can be seen. Because of the overlap of said absorption bands, the water band appears as the left shoulder of the broad band.
- a comparison and interpretation of the NIR spectra is expediently carried out over the entire recorded spectral range. This is done with the multivariate data analysis MDA.
- MDA multivariate data analysis
- several statistical variables are typically examined simultaneously. For this purpose, the number of variables contained in a data set is reduced without at the same time reducing the information contained therein.
- thermoset compositions such as SMC molding compositions
- an examination of the state of maturity through a covering here an examination of the state of maturity through a covering (here carrier film) must take place.
- a covering here carrier film
- thermosetting resins After covering this resin layer by means of a further carrier film, this sandwich-type arrangement passes through a roller path in which impregnation of the fibers and compaction of the semifinished product to be obtained are achieved.
- NIR spectroscopy enables non-destructive, real-time measurement of the viscosity of the ripening thermosetting composition.
- the precured resin layer is e.g. not covered by a polymer film, so that a direct irradiation of the pre-cured resin layer can be done with NIR radiation.
- a material layer covering the precured resin layer such as e.g. A polymer film Only in this way is a meaningful evaluation possible, because a film has, depending on the material in different areas absorption bands, the bands of the thermosetting resin can overlay and / or cover. This makes an evaluation more difficult, in the worst case even impossible. Without a slide, this problem does not exist.
- the reference sample with a known degree of crosslinking of the precured resin layer comprises a resin layer provided on a carrier material, wherein carrier material and resin layer of the Reference sample are similar to the sample of support material and resin layer to be measured.
- the determination of the degree of crosslinking of the precured resin layer of the at least one reference sample after the precuring of the resin layer is carried out on the basis of at least one individual sample taken from the precured reference sample. It is preferred if the degree of crosslinking of the precured resin layer of the reference sample is determined based on at least one, preferably at least two, three, four or more, the reference samples taken individual samples according to the VC test.
- a sample typically 10 x 10 cm
- the sample is weighed again.
- the final weight is determined from the final weight and given as a percentage value.
- the previously determined paper weight serves as the basis for the determination of the resin application in percent ((final weight - paper weight / paper weight) x 100).
- the calibration is performed by recording an NIR spectrum from a precured reference sample, which is then tested for the right humidity by VC test.
- various reference samples are provided with differently precured resin layers, wherein the degree of precuring can be varied by different drying times and temperatures.
- an average value is formed, which is assigned to the respective NIR spectrum.
- several reference spectra of coated plates with different color decors and different degrees of cure are recorded. From the reference spectra, a calibration model is created, which can be used to determine the degree of precure of an unknown sample. In the (in-line or off-line) NIR measurement, the result of the VC test or quality of the precure is then directly predicted.
- multivariate data analysis is performed using the partial least squares (PLS regression) method, which allows a suitable calibration model to be created.
- the evaluation of the data obtained is preferably carried out with a suitable analysis software, such as with the analysis software SIMCA-P from Umetrix AB or The Unscrambler from CAMO.
- This program allows, among other things by special pretreatment techniques of the spectral data, various interference factors on the measurement such as surface texture of the samples, infrared-inactive fillers in the coating or different colors of the samples and more, to minimize.
- the carrier material is in the form of a carrier plate, paper layer, film layer or fabric layer.
- a paper layer e.g. Overlay papers, decor papers, or kraft papers are used.
- Overlay papers are thin papers which are typically already impregnated with a conventional melamine resin. Overlay papers are also available in which abrasion-resistant particles, such as corundum particles, are mixed into the resin of the overlay in order to increase the abrasion resistance.
- abrasion-resistant particles such as corundum particles

- the carrier material is partially or completely impregnated with the resin, wherein the resin penetrates or penetrates into the carrier material.
- An impregnation takes place in particular when using paper layers as a carrier material.
- the term "impregnation” means a complete or partial impregnation of the paper layer with the resin.
- Such impregnations can be applied, for example, in an impregnating bath, by rolling, by anilox rolls, by knife coating or also by spraying.

- MDF medium density fiber
- HDF high density fiber
- OSB coarse chip
- WPC plate wood plastic composites
- the surface of the support material may be surface treated, e.g. in the case of a wooden support plate, the surface may be abraded. In the case of a plastic carrier plate, the surface may be corona treated.
- the precured resin layer can accordingly be present as a liquid overlay on a carrier plate or as a partial or full impregnate of a paper layer.
- the at least one precured resin layer provided on a carrier plate has a thickness of between 10 and 150 ⁇ m, preferably between 20 and 100 ⁇ m, particularly preferably between 30 and 80 ⁇ m.
- the resin layer may comprise at least one layer, preferably at least two layers, in particular preferably at least three layers applied one after the other.
- the precured resin layer comprises a resin from the group comprising a) at least one thermosetting resin and / or b) at least one UV-curable and / or electron-curable (ESH) resin.

- the radiation-curable paints used contain methacrylates, e.g. Polyester (meth) acrylates, polyether (meth) acrylates, epoxy (meth) acrylates or urethane (meth) acrylates.
- the acrylate or acrylate-containing lacquer used contains substituted or unsubstituted monomers, oligomers and / or polymers, in particular in the form of acrylic acid, acrylic ethers and / or acrylic acid ester monomers, oligomers or polymers.
- the degree of crosslinking of the at least one precured resin layer is determined within (in-line) and / or outside (off-line) a production line of the substrate material provided with the precured resin layer.
- the measuring head which picks up the spectra, can be positioned anywhere on the production line. It delivers several readings per impregnation or plate / laminate etc. By traversing the measuring head over a plate width, differences can also be detected here.
- both mobile and stationary NIR meters can be used.
- the present process can be used for various resin systems (such as epoxy, PU, polyamide, etc.), depending on the resin system, one or more peaks must be selected that allow a statement about the state of curing.
- resin systems such as epoxy, PU, polyamide, etc.
- the present method has a number of advantages: on-line measurement possible; any synthetic resins are analyzable; mobile and fast measuring method; Production control possible.
- impregnated papers for the calibration of the NIR measurement, first impregnates are measured in different drying states with the NIR detector. For this purpose, impregnates are taken from an impregnation channel which had been produced at different speeds. The speeds were varied by the known optimum up and down. Then the samples were measured by NIR and then the VC value determined in the oven. After drying for five minutes, the hardened final state (C state) is reached. After drying in the oven, the samples are measured a second time using the NIR measuring head. This measurement provides the end point of the drying.
- the recorded NIR spectra (see FIG. 1 ) of the individual orders show a similar course with a broad absorption band at 1490 nm. This band corresponds to the first harmonic of NH bonds of the melamine-formaldehyde resin. At 1450 nm, another band is visible, which corresponds to the first harmonic of the OH bond of the water.
- the water band appears as the left shoulder of the broad band.
- the main difference in the spectra is the height of the baseline.
- the shift of the baseline is due to the different degrees of cure (density, refractive index) of the two samples.
- the spectrum of the sample after drying in the oven shows lower absorption values than before drying, because the incident light is reflected or scattered more strongly. This makes the spectral differences due to the chemical change of the samples hardly or not recognizable.
- the compensation of the disturbing scattering effect can be achieved by various methods of data pretreatment.
- the spectra show changes in the absorption intensity of the bands at 1450 nm (water) and at 1490 nm (NH groups).
- the creation of the calibration model which describes the relationship between the NIR spectra and the associated VC values, is carried out using multivariate regression methods (eg with MLR PCR, PLS, etc.).
- the evaluation is carried out over the entire spectrum. The longer the sample is dried in the oven, the higher the degree of crosslinking. It can also be measured samples that have a higher VC value than usually sought.
- improved control of the impregnation channel (drying channel) can also be achieved.
- the undried samples have a methylol group content above the optimum, the overdried ones have a methylol group content below the optimum.
- the tests on the hardening state can be carried out directly at the outlet of an impregnation plant.
- the NIR measuring head delivers several hundreds of measured values per minute, enabling continuous process monitoring. For quality checks in the warehouse, it is possible to operate with a mobile measuring device.
- the NIR measurement of the cross-linking can be done directly on the production line (in-line measurement) with a mobile device (DA 7400 Fa. Perten) or in the laboratory (off-line measurement) with a stationary device (DA 7250 Fa. Perten).
- an overlay (paper weight: 25 g / m 2 ) was impregnated with a mixture of melamine resin and corundum. The total order amount was about 75 g / m 2 , of which about 55 g were melamine resin.
- the impregnation channel was with different Speeds driven. Samples were taken from the individual speed variants and measured using the NIR measuring head. Then they are examined for their VC value. In this case, VC values of 3.0 to 8% were found. All samples are measured a second time after drying with the NIR measuring head.
- this method can also be used in systems in which the pre-cured resins are applied directly to printed or unprinted wood-based panels.
- These plates have the same problems as impregnated papers. Again, it is important to know the curing state of the resin on the plate. This applies both to a linked production line in which after the resin application and drying directly further processing in a KT or Conti press takes place as well as in a non-linked production in which takes place after the resin application and drying an intermediate storage. In the case described, the determination of the state of crosslinking is even more important since, in contrast to impregnated papers, a determination of the quality of the parameters usually to be determined is otherwise hardly possible.
